Can the Manufacturing Cost be Reduced with a 0.3 mm Sheet Magnet

Can using 0.3 mm sheet magnets reduce manufacturing costs? Many manufacturers are looking for answers to this question, seeking to find more cost-effective solutions for their promotional products. However, it is necessary to carefully evaluate what results thin sheet magnets, especially those with a thickness of 0.3 mm, will give in production.

In the production of adhesive magnets, double-sided tape is applied to the back of the sheet magnet. The raw material, quality and application method of the tape are very important for this method to give a quality result (for detailed information see: Sheet Magnet, Can Adhesive Magnet Be Made with Double Sided Tape?) Not all double-sided tapes have the same effect, so the choice of tape is critical.

For promotional fridge magnets and hobby magnets, 0.4 mm is usually used as the minimum thickness. The reason for this is that there is a serious loss in the magnetic attraction power of the thinner 0.3 mm magnet. While using 0.3 mm sheet magnets may seem tempting to reduce costs, this practice results in up to a 25% reduction in product quality. Manufacturers should pay attention to this point, considering the attractiveness of magnets and product quality.

The 0.3 mm magnet can only give successful results with paper and similar lightweight materials. However, when used with non-paper products, it will be inefficient due to weak magnetic strength. Therefore, 0.4 mm or thicker magnets should be preferred for hobby magnets, refrigerator magnets and other similar products.
